2,3-Dimeth oxy-10-oxostrychnidinium 3-carboxy benzoate trihydrate: the 1:1 proton-transfer compound of brucine with isophthalic acid
MetadataShow full item record
The structure of the title, compound C23H27N2O4+烸H5O4糈2O, has been determined at 130 K. The hydrogen isophthalate anions and the water mol�ules (one of which is disordered over two approximately equal sites) associate through extensive hydrogen-bonded inter�tions, including those with the common undulating brucinium cation layer substructures, forming a three-dimensional framework structure.
